Yes! All materials are tileable.

The materials follow the Disney Principled BSDF model and are fitted to match real-world fabric scans as closely as possible.Even though fabrics are non-metallic, optimizing the metalness map, along with other PBR parameters, gives the fitting algorithm more flexibility, resulting in a better match to the captured appearance.Constraining metalness to zero would increase fitting errors, so we allow small variations to achieve a more accurate final render.It's important to treat all maps as a unified system: the true material appearance comes from using the full set together.
